A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-1Designing and planning a cloud solution architecture

The EHR Healthcare team is setting the availability design target for the customer-facing systems that hospitals and insurance providers reach. What floor does the stated business requirement put on those systems?

A minimum of 99.9% for customer-facing systemsCorrect · your answerCorrect. The floor covers everything a customer touches.
99.99% availability across two separate regionsFour nines is a stricter target than this business asked for.
Best effort uptime outside maintenance windowsA numeric floor was written down, so effort is not the measure.
Full uptime with no unplanned service outageNothing here promises service without interruption.

Correct.

Concept

A published availability figure is a constraint on the design rather than an aspiration, and it has to hold at the weakest link in the serving path.

Why A

The business requirements list a minimum 99.9% availability for all customer-facing systems, next to faster provider onboarding, centralized visibility, lower latency and regulatory compliance.

Source

Business requirements On-board new insurance providers as quickly as possible. Provide a minimum 99.9% availability for all customer-facing systems.
